A galvanometer is an electromechanical measuring instrument for electric current. Early galvanometers were uncalibrated, but improved versions, called...

A ballistic galvanometer is a type of sensitive galvanometer; commonly a mirror galvanometer. Unlike a current-measuring galvanometer, the moving part...

A mirror galvanometer is an ammeter that indicates it has sensed an electric current by deflecting a light beam with a mirror. The beam of light projected...

A vibration galvanometer is a type of mirror galvanometer, usually with a coil suspended in the gap of a magnet or with a permanent magnet suspended in...

A string galvanometer is a sensitive fast-responding measuring instrument that uses a single fine filament of wire suspended in a strong magnetic field...

adjusted until the bridge is "balanced" and no current flows through the galvanometer Vg. At this point, the potential difference between the two midpoints...

scale in proportion to the voltage measured and can be built from a galvanometer and series resistor. Meters using amplifiers can measure tiny voltages...

than has ever been built before, under the trademarked name of Physio-galvanometer, or O-Meter. It has very little in common with the old type E-Meter....

galvanoscope, frog galvanometer, rheoscopic frog, and frog electroscope. The device is properly called a galvanoscope rather than galvanometer since the latter...

The thermo-galvanometer is an instrument for measuring small electric currents. It was invented by William Duddell about 1900. The following is a description...
